Orcust Deck #773611 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: master-duel

Legality

Main 44 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Orcust Link and Xyz bosses (Karmael, Ophion, Dark Rebellion, Malevolent Scythe, Rusty Bardiche, Raider's Knight) built from Orcust Harp Horror and Girsu chains; the core Orcust Link boss set (Galatea, Enlilgirsu, Dingirsu) is largely absent.; Phantom Knights Xyz and Link pressure from Decayed Cloak, Doomed Soleret and Torn Scales recursion.
• Turn 1 (going first): Open Harp Horror, Girsu or a Phantom Knights starter, chain through GY-banish summons into a Link or Xyz boss while protecting the line with Ash Blossom and Ghost Ogre.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Droll & Lock Bird, Maxx "C" and Dominus Impulse as hand traps against the opponent's first summon, then convert the surviving starter into a boss.
• Recovery: Recur Phantom Knights and Orcust monsters from GY and banishment (Harp Horror, Cymbal Skeleton, Decayed Cloak, Silent Boots) and re-threaten with Mulcharmy draw effects.
• After siding: Not applicable: Master Duel is single-game and the deck runs no Side Deck.

Why it scores here

The deck reliably opens a starter: three copies each of Orcust Harp Horror, Girsu and the Phantom Knights starters give roughly a 31% chance of at least one per 5-card opening hand, and the searcher text count of 9 lifts that to about 70% per hand. Its interaction layer is dense (11 negation and 26 removal-text cards, 8 hand-trap-tagged cards, and about 72% chance of at least one hand trap in a going-second 6-card hand), which keeps a starter alive long enough to convert. Conversion is the weak point: no recorded boards exist, so the ceiling and median are text-only inference, and 10 of the 25 usage-core cards (including Galatea, Enlilgirsu and Dingirsu) are missing, which splits the deck between Orcust and Phantom Knights engines. Popularity of the Orcust archetype did not earn points, the deck has no side and no meta share, and the score was built from consistency, interaction and boss quality at the system level rather than by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 59.6, Going First ≈ 62, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: engine split across Orcust and Phantom Knights (-3); no side deck in a single-game format (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated meta sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.31 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Three copies each of the two main starters (Harp Horror, Girsu) and three Phantom Knights starters give repeatable access
• Dense hand-trap and negation layer (Ash Blossom x3, Ghost Ogre x2, Droll x2, Maxx "C", Dominus Impulse x3) supports going second
• Multiple 2100–2600 ATK bosses across Xyz and Link

Weaknesses

• 10 of 25 usage-core cards missing, including Galatea, Enlilgirsu and Dingirsu
• Mixed engine (Orcust, Phantom Knights, Mekk-Knight, Mulcharmy) lowers combo coherence
• No Side Deck, so no adaptation in a single-game format
• Single-copy support slots (15 singletons) raise the brick risk for the Extra Deck link requirements

Critical choke points

• Orcust Harp Horror and Girsu (three copies each) are the main starter route; losing them to a hand trap leaves few backups
• The Extra Deck link chain depends on Link monsters that are not in the Orcust core list

Recommended changes

Evidence & confidence

• Verified: Legal under the Master Duel size rules: 44 Main, 15 Extra, 0 Side; Restricted cards at or below legal copy limits: Crossout Designator, Foolish Burial, Maxx "C", Reinforcement of the Army (Limited, 1 each); Droll & Lock Bird (Semi-Limited, 2); Exact-archetype purity 16.9%; 15 of 25 usage-core cards present
• Observed: Usage statistics show 100% inclusion for Foolish Burial, Maxx "C", Ash Blossom, Girsu and World Crown in this archetype
• Inferred: Starter access ≈ 0.31 per triple-copy starter and ≈ 0.70 for searcher text (hypergeometric); Going-second hand-trap coverage ≈ 0.72 (hypergeometric); Interaction density and boss closing power read from card text
• Provisional: Meta Power (no dated metagame sample); Matchup fit and tournament reliability (no tournament link); Post-side plan (Master Duel is single-game)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null, and the Master Duel format runs no Side Deck, so post-side scoring is not applicable
